" A nauw filed January 5,1903. sin-tn 110,137,945. (N0 model.)

To all whom/it may concern.-

Be it known that I, WILLIAM J. BAKER, residing at Southgate, in thecounty of Campbell and State of Kentucky, have invented a new andImproved Pliers for Clamping Clips on Wires, of which the following is aspecification.

My invention seeks to provide a simple and easily-operated pliers forlocking clamps or clips around wire strands, and more particularly foractingon that formjof clip or wire clamp disclosed in my pendingapplication filed March'lS, 1902, Serial No. 98,868.

My invention in its generic nature comprehends a pair of plier-j'awslinked together and having inwardly-extending opposing teeth orprojections and a movable bed for supporting the clamp or clip memberand moving it up into a desired position relatively to the projectionsof the jawsas they close against the said clip-tongue.

In its more complete nature my invention embodies a peculiar cooperativearrangement of the plier-jaws, link-bars for joining them, an anvil orbed-plate movable vertically and automatically as the jaws close, and apair of opposing clip-tongue-turning plates connected one to each jaw,and means forming a part of said plates for engagingthe anvil orbedplate to move it toward the opposing intermeshing facesand theturning-plates as they close on each other; and in its still moresubordinate features myinvention consists of certain detailsof-construction and peculiar com bination of parts, all of which willhereinafter be fully described,and specifically pointed out in theappended claims, referencebeing had to the accompanying drawings, inwhich- Figure 1 is a perspective view of my im-v proved pliers, the jawsbeing shown in their closed position. Fig. 2 is a side view, the

jaws being open and the clamp memberor clip and the wires being shownsupported thereon. Fig. 3 'is' a vertical longitudinal section of thesame, the jaws being closed and the clip member closed over the wirestrands. Fig. 4" is a detail view of the jaws'detached. Fig. 5 'is adetail View of the vertically-movable anvil or bed-plate. Fig. 6 is'aplan view of the same, the jaws being open. Fig. 7 is a detail view ofone of the clip members. Fig.

ment of the jaws.

To the inner or clamping face of the head a is fixedly mounted adie-plate O, bifurcated at the lower end to form inwardly-projecting;ears 0 c and provided at the upper edge at the opposite ends withinwardlyextending projections or teeth 0 c, disposed approximately atright angles to the body portion 0 To the head I) is secured a dieD,which opposes the die 0, and the said die D has a centrally-disposedlug 01, adapted to extend between the ears 0 c of the plate D when thejaw-heads are closed together, and the said lug has its upper. edgebeveled, as at 01 to form a cam member, the purpose of which willpresently appear.

At the upper edge the die D has a single central projection or tooth dadapted to extend between the projections c c in the opposing die C whenthe heads are closed, the said projections c c and d being arranged tointerlap, as clearly shown in the drawings.

. E E designate a pair of horizontally-disposed links that straddle thecross portions of the jaws, one of said links being on each side of thejaws and pivotally connected with the jaw-heads, as at e e, and eachlink is also formed with a vertical groove e on the inner face at apoint midway the ends.

Now comes an essential feature of my invention, being that of the anvilor bed-plate,

which moves automatically upward in a direction against the projectionsc c and CF, whereby to rigidly hold the clip and the wires in place asthe opposing dies D and 0 close against and turn the tongues of. theclips from the wirestrand or strands. V

The anvil or bed-plate F consists of a fiat horizontally-disposed memberhaving a length equal the width of the jaws and integrally formed with apair of oppositely-disposed legs f f, which are guided by the links Eand move vertically in the grooves e thereof, and

the lower ends of the legsfhave outwardlyprojecting heel portions f fthat limit the upward thrust of the member F and prevent its becomingdetached or dropping out when the jaws are wide open.

The particular form of clip or clamp member hereinafter referred to andillustrated in Fig. 7 essentially comprises a base portion 1, a centralportion 2, bent up at one side, and a pair of end tongues 3, bent up atthe opposite ends of the other side, and it may also havecentrally-disposed short bentup tongues 4 in transverse alinement withthe tongues 3, which are intended to project between the wire strands;but the tongues 4 may be omitted without affecting the desired purposesof my invention.

I11 operation the clip G is placed on the anvil F, as shown in Fig. 2,with its central tongue against the central tooth or projection d on thedie D and with its end projections 3 against the end teeth orprojections 0 on the die 0, after which the two wire strands 5 5, whichare straight or curved, are seated in a horizontal plane on the clip G,as clearly shown in the aforesaid Fig. 2. Now by closing the jaws themember 01 will press against the clip-tongue 2, while the projections cc similarly engage the clip-tongues 3 3. As the two jaws close thecam-lug (Z on the member D engages the under side of the member F of theanvil and forces the said anvil upward toward the interlappingprojections c c and (1 simultaneously with the inward or closingmovement of the jaws, and thereby firmly compresses the clip-bottom withthe wires against the under side of the said projections c c and d andfirmly holds the clip-wires in a desired rigid condition to permit of aneffective and close bending of the tongues 2 and 3 over the wires tofirmly clamp them together in the manner clearly shown in Fig. 8.

While I have shown my appliance as particularly adapted to clamp uponthe wires the special construction of clip shown, it is manifest thecorrelative positions ot the interlapping projections on their twoopposing dies may be varied or modified to suit clips having a diiferentarrangement of vertical projections or tongues without departing fromthe scope of the appended claims.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A pliers for clamping clips on wires, comprising a pair of jawslinked together, said jaws being provided with projections adapted tointerlap when they are closed, and an anvil or bed-plate looselysupported on the jaws under the interlapping projections, for thepurposes stated.

2. A pliers for clamping clips onto wires,

described.

comprising a pair of jaws linked together and provided with projectionsadapted to interlap when the jaws are closed, an anvil or bedplateloosely supported on the jaws under the interlapping portions andautomatically movable toward the said projections when the jaws areclosed, as set forth.

3. A pliers for clamping clips onto wires, comprising a pair of jawslinked together, said jaws being provided with projections adapted tointerlap when the jaws are closed. an anvil or bed-platelooselysupported on the jaws under the interlapping projections, andmeans for automatically moving the said anvil or bed-plate toward thesaid projections when the jaws are closed, as set forth.

4. An appliance for the purposes described, comprising a pair ofopposing plier-jaws, links pivotally connected at their opposite ends tosaid jaws, a die-plate on each jaw, said die-plates having projectionsadapted to interlap with each other when the jaws are closed, one of thesaid die-plates having a cam portion, a bed member for supporting' theclip and the wires as they are acted on, and having movement verticallybetween the jaws and adapted to be engaged by the aforesaid cain portionand moved upward as the jaws are closed, for the purposes specified.

5. An appliance as described, the combi: nation with the opposing jawshaving projections adapted to interlap when the jaws are closed, linkmembers, one on each side of the 5 jaws pivotally connected at theirends to the said jaws, each of said link members having a verticalgroove on its inner side; of the anvil or bed-plate F comprising ahorizontal member adapted to support the clip and the [00 wires, andpendent legs to slidably engage with the grooves in the link members,and means for automatically moving the die upward as the jaws areclosed, as specified.

6. The combination with the jaws, the link :05 members E pivotallyconnected at their ends to the jaws, each of said members having avertical groove on its inner face; of the anvil or bed-plate F,comprising a horizontal portion adapted to support the clip and the nowire strands when acted on, pendent legs slidably mounted in the groovesof the links, said legs having outwardly-turned stop members at theirlower end and means carried on one of the jaws for engaging the said dieor I I5 bed plate to move it in the direction of the clamping-faces ofthe jaws when the said jaws are closed together, all being arrangedsubstantially as shown and for the purposes WILLIAM J.
